HONDA CLAIM RULE For GX160 QMA Type Engines, 1 All engine claims must follow procedure listed in QMA rulebook Please see Article 6 Section 1. HONDA SUSPENSIONS, 1 All suspensions must follow procedure listed in QMA rulebook Please see Article 6 Section 2. NOTE All shipping is to Express Mail at the shipper s Expense. 4 For the purposes of this rule only if a handler has multiple cars competing in the Honda class GX120 or GX160 at one race. event and more than one engine is found to be illegal at that event it will be considered to be one offense. 5 Refusal of tech shall be interpreted as an admission that the engine is illegal and a suspension from the Honda class will be. immediate with all awards qualifications being revoked. 6 Confiscation of part or parts only the illegal part and all related parts and not the whole motor will be confiscated A full motor. tear down is required if an illegal part is found,GENERAL RULES. 1 Only stock Honda GX160 UT 2 HX2 serial beginning with GCBPT engine and gearbox will be used in this class All. parts will be stock Honda specifically made for the Honda GX 160 UT 2.

FLYWHEEL FAN AND IGNITION SYSTEM, Caution should be used when removing flywheel Do not hit with hammer or other heavy objects. Service manual show flywheel to be removed with commercially available 6 puller Another method is. inertia type knocker that threads onto crankshaft end. The transistorized magneto ignition is fixed at 20 degrees BTDC and may not be altered in. any way Firing must not exceed 0 104 or 20 degrees BTDC. Quick check Turning flywheel clockwise if the leading edge of the depression of flywheel rim. where the magnet is mounted is not still under the right hand coil leg at0 115 BTDC it is probably. illegal and should be checked further If timing needs to be checked further see page 19. A Flywheel keyway or its position must not be altered. B Key may not be deleted or altered in any way, C Magnet and its position may not be altered in any way. D Magnet retaining screw may not be altered in any way Screw may not be replaced with larger. or smaller screw No heli coiling of mounting hole, E Ignition coil or its position other than air gap may not be altered in any way Coil mounting. bolts must be stock and cannot be altered in any way to advance or retard timing Coil attaching. bolts will be stock 6mm cap screw l 1 16 long There can be no more than 3 8 of unthreaded. portion of bolt that does not measure 0 230 diameter This restricts movement of coil to a. position that could make ignition timing illegal If a coil support mount becomes stripped it is. permissible to heli coil However only one leg may be repaired if both legs are heli coiled the. crankcase becomes illegal, F All nylon blades on the cooling fan must be intact.
